Application filed December 22, 1916. Serial No. 138,434.

To all whom it may concern: V

Be it known that I, FRANK A.WE1BB, a citizen of the United States, residing at Protection, in the county of Comanche and State of Kansas, have invented certain new and useful Improvements in Carbi'd Controlling and Dumping Valves for Acetylene-Gas Generators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in carbid controlling and dumping valves for acetylene gas generators.

The object of the present invention is to improve the construction of acetylene gas generators and more especially the construction of the carbid holder and the carbid controlling and dumping valve and to provide a simple, practical and eiiiclent valve of this character ca able of discharging a charge of carbid of the same size at each operation and equipped with means for cutting off the supply of carbid to the valve when the valve is inclined upwardly at any angle to the horizontal whereby the loss of carbid is prevented in case the valve should stick in any position from a horizontal to a full dumping position.

Another object of the invention is'to provide a carbid controlling and dumping valve of this character which will not discharge when in a horizontal position or any position between a horizontal and its full closed position.

lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended: it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the splrit or sacrificing any of the advantages of the invention.

- In the drawing- Figure l is a vertical sectional view of a portion of a carbid holder and a carbid controlling and dumping valve constructed in accordance with this invention,

Fig. 2 is an elevation of the same, in the position shown in dotted lines in Fig. 1,

Fig. 3 is a detail perspective view of the carbid controlling and dumping valve,

Fig. 4 is a detail sectional view illustrating the arrangement of the combined stop and reinforcing plate.

F 1g. 5 is a vertical sectional view. illustrating another arrangement of the plate or partition.

Like numerals of reference designate corresponding parts in the several figures of the drawing. p

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates an automatically operated carbid controlling and dumping valve composed of spaced side walls, a connecting bottom 2, and a curved rear end wall 3. w The valve 1 is connected by a transverse pintle 4 to the lower tapered portion 5 of a carbid holder of an acetylene gas generator. The tapered portion 5 is flattened at two of its side walls and it is provided at one of its walls with an outlet 6 and the opposite wall 7 has an inclined portion 8 extending downwardly from the bottom of the outlet and having a transversely disposed eye 9 for the tle or pivot i. The plntle or pivot 4 extends through the side walls of the carbid dumping and controlling valve which eX- tends in advance and in rear of the pintle or pivot-and the forwardly extending portion is cut away at the side walls at 10 to form a discharge mouth or spout. The valve 1 extends downwardly and rearwardly at an inclination as illustrated in full lines in Fig. 1 of the drawing when in a. non-feeding or carbid receiving position and it assumes an oppositely inclined position as illustrated in dotted lines in Fig. l of the drawings when in a feeding or carbid discharging position. The valve has a receiving end and a discharging end. When the valve is in carbid receiving position its receiving end is lowermost, and when the valve is in carbid discharging position its discharging end is lowermost. In order to enable the valve to deliver or discharge a charge of carbid of the same size at each operation, and prevent any leakage of the carbid from the carbid holder to the valve should the valve for any reason stick in its feeding operation, the valve is provided with a plate or partition 11 extending across the said valve midway between the upper and lower edges of the side walls and fixed to .the same and arranged in parallelism with the bottom wall or portion of the valve. The plate or partition 11 is mounted reception of the pineccentrically with relation to the transverse pin or pintle with its inner edge arranged contiguous to the transverse eye of the pivot or hinge joint and in the pivotal movement of the valve the plate or partition travels in an arc around the pivotal pintle and is adapted to cut off-the supply of carbid to the valve when the plate or partition and the rear portion of the valve is inclined upwar-dly at anylangle to the horizontal.

When the valve is inclined in the opposite direction the bottom wall or portion 2 will prevent any feeding of the carbid to the acetylene gas generator. By this construction the feed of carbid to the machine is positively controlled and leakage of the carbid and'gas is prevented.

The plate or partition 11 is preferably of an area substantially equal to the area of the outlet 6 of the carbid holder and the transverse pin or pintle is arranged in the vertical plane of the lower edge of the wall v12 at top of the outlet 6. Also the pivot or pintle is arranged midway between the upper and lower edges of the side walls of the valve and the curved rear wall is arranged on an arc of a circle having its center at the outer or rear edge of the plate or partition and the said curved arcuate rear wall is preferably approximately 25 degrees less than a semi-circle but the proportions of the parts may be varied as will be readily understood. Vi hen the valve is in its nonfeeding position as illustrated in full lines in Fig. 1 of the drawin the carbid from the carbid holder will ow into the valve until the latter receives a full charge and when the valve is operated to dump the charge, the plate or partition will move upwardly as the mouth or discharge end of the valve'moves downwardly and the supply or feed of the carbid will be cut off to the valve while the valve is in its feeding position. The spout or front end of the valve is connected by a transverse pintle 13 with the lower end of an operating rod 14 designed to be connected with the hell not shown or other operating member of the acetylene gas generator and when the rod moves downwardly with respect to the valve, the latter will be opened or moved to its seating position and when the operating rod is raised the valve will be carried to its non-feeding position. The inclined bottom portion 8 of the wall 7 'at the outlet of' the carbid holder is equipped at its lower outer face with a combined reinforcing and stop plate 15 suitably secured to the inclined portion 8 and havin the side edges 16 bent at right angles to orm projecting flanges which are arranged in the path of and adapted to be engaged by the pivot 13 of the operating rod 14:. The valve is equipped at its rear end with a weight 17 which.

to its non-feedm' g 'osition after a char e has been dumped. p g

In Fig. 5 is illustrated another form of the invention in which the plate or-partition 11" is arranged at an angle to the bottom of the pivoted valve. The plate or partition extends downwardly and rearwardly from the transverse pivot or pintle of the valve when the bottom of the latter is in a horizontal position and it has been found that the plate or partition may be arranged at such an inclination variable from five to fifteen degrees more or less.

What is claimed is I 1. In combination, a carbid holder having a discharge opening, a downwardly inclined extension carried by said carbid holder and disposed below said discharge opening, a valve having a receiving and a discharge end and horizontally pivoted intermediate its ends to said extension, said valve being adapted to be moved into, an inclined carbid receiving position with its receiving end lowermost and into a reversely inclined carbid discharging position with its discharging end lowermost, a weight normally holding the valve in carbid receiving position, a cutofli' plate carried by said valve and having one of its longitudinal edges contacting with the lower edge of said extension when the valve is in carbid discharging position, a rod extending transversely of and carried by the valve and adapted to engage the under side of said extension to limit the movement of the valve under the influence of said weight, and an operating rod connected to said rod.

2. In combination, a carbid holder having a discharge opening, a downwardly inclined extension carried by said carbid holder anddisposed below said discharge opening, a valve horizontally pivoted intermediate its ends to said extension and having a carbid receiving end and a carbid discharge end', a cutoff plate carried by said valve and having one of its longitudinal edges contacting with the lower edge of said extension, and means adapted to move the valve into carbid receiving positionand into carbid discharging position, said cutoff plate being located inthe plane of said ex- FRANK A.
